I know at least one case when linking against pthread is not acceptable. It is when use any other threading library than libpthread. E.g. we often use home-made non-preemptive thread library because it better fits our needs than pthreads. It is absolutely incompatable with pthreads and if linked together will cause segfault on any 'new' (or 'malloc') operator. I guess (but I am not sure) that using of alternative thread libs such as NGPT will also cause problems.
